WIRE-NAIL MACHINE.

PECIFIGAIION forming part of Letters Patent No. 340,887, dated April 27,1886.

Application filed September-$15, 1885. Serial X0. 179,141. (No model.)

To aZZ whom it may concern: glc-joints 7', which operate the parts or(lies I. Be it known that I, )LINTON LOVELL, of 76, whereby the sectionsof wire cut off by the Boston, in the county of Suffolk and State ofcutters h h are divided into two parts, and Massachusetts, have inventedcertain new and whereby points are formed on both parts, as usefulImprovements in \Vire-Nail Machines, described in the Lewis patent.

Four headers or hammers, at,two for each This invention relates to machines for makwire-cutter 71,and each pair of severing and ing wire nails, and is an improvement onthe pointing dies 7.:,are employed to form heads on invention shown inLetters Patent of the the ends of the lengths of wire, as described inUnited States No. 328,23 granted to N.

The

end of the lever. The lever c is connected by spring 12 bears at itscentral portion on the 50 rods 2' i at opposite sides of its pivot withtogcurved wall ofthe cavity in theframe, in which said spring iscontained, its ends being thus adapted to yield and allow the detents SS to move backwardly.

I I represent arms secured at their lower ends to holders I, which aresupported by levers L L pivoted to the frame a, said levers beingconnected by rods M with the lever c. The motion of the lever coscillates the levers L L, which move the arms I I up and down. Saidarms have hooks 6 at their upper ends, which project over the lengths ofwire when the arms I are raised, as shown at the left in Fig. 1. IVhenthe arms I are lowered, the hooks 6 bear upon the wire and force it downalong the ends of the yielding latches 8, and along the sides ofyielding arms 9, below the said latches, said arms being pivoted at 13to the supporting-frame and pressed outwardly by springs bearing on rodsor pins 14, interposed between them and the arms 9, as shown in dottedlines in Figs. 6 and 7.

The latches 8 and arms 9 constitute detents or brakes that bear againstthe lengths of wire while they are being depressed by the hooks 6 untilthey nearly reach the supporting-rods i, the lengths of wire being thusprevented from falling by gravitation, and. perfectly controlled whilemoving from one position to the other.

Springs K, secured to the holders 2" and le vers L, draw said holdersback, so as to press the upper ends of the arms I against the lengths ofwire.

The arms I have hooks 7 below the hooks 6, to remove the completed nailsfrom the dies in case said nails stick to the dies,

I claim The combination of the cutters which sever the wire-lengths fromthe main wire, the severing and pointing dies located below the cutters,and means, substantially as described, for holding said lengths duringtheir movement from the cutters to the dies, as set forth.

In testimony whereof I have signed my name to this specification, in,the presence of two subscribing witnesses, this 26th day of August,1885.

CLINTON LOVELL.
